SIDNEY H. NEXVBEERY, OF CHESTER, PENNSYLVANIA.

DEVICE FOR OPERATING AND LOCKING- A SWINGING WINDOW SASH.

Application filed August 6, 1921.

To all whom it may concern Be it known that l, SIDNEY H. NEW- BERRY, a citizen of the United States, residing in Chester, in the county of Delaware, State of Pennsylvania, have invented a new and useful Device for Operating and Looking a Swinging Window Sash, of which the following is a specification.

My invention relates to means for operating a swinging window sash for ventilating and opening purposes and for locking the same in open and closed positions, and it consists of a bar pivotally connectible with one sash and laterally movable in the arc of a circle and adapted to be applied to a plate'like member on the other sash, and a device on said bar adapted to contact tightly with said plate like member in the various positions thatthe bar may occupy in the various positions of the swinging sash, thus locking the bar and consequently the swinging sash.

It consists also of means for controlling the bar in the closed position of the swinging sash. V

The invention is satisfactorily illustrated in the accompanying drawing, but the im portant instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figure 1 represents a horizontal section of a portion of a device for operating and locking a swinging window sash on the line 1 1 Figure 3, in the closed position of the sash.

Figure 2 represents a vertical section thereof on line 2-2 Figure 4 in the open position of said sash.

Fig. 3 represents a top or plan view of the device in the closed position of the sash, on a reduced scale.

Figure 4 represents a top or plan view of the device in the open position of the sash on a reduced scale.

Figure 5 represents a plan view of a detached member of the device on the scale of Figure 1.

Figure 6 represents a side elevation of the device shown in Figure 5.

Figure 7 represents a side elevation of a portion of the bar employed, and a dog thereon for locking said bar with a member on the lower sash.

Serial No. 490,281.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 and 2 designate the upper and lower sashes of a window, the upper sash being mounted by the pivot 3 onthe window frame 4: whereby said sash 1 may be swung out for the purpose of opening and ventilation, said sash being also adapted to be closed as usual.

Connected with a side of the meeting rail 5 of the upper sash is the eye 6 with which is freely connected as a knuckle the adjacent end of the bar 7 in whose opposite end on the underside thereof is the recess 8 ad jacent to which is the dog 9 which is connected with said bar 7 by the pivot 10 and provided with the handle 11 whereby said dog may be operated to raise and lower the head portion 12 of the dog, said portion being somewhat cam shaped.

Connected with a side of the meeting rail of the sash 2 is the upright plate 13 which is preferably of angular form, its lower limb resting on said meeting rail and being secured thereto, it being noticed that when the upper sash is swung out the position of the recess 8 in the bar 7 is such that said recess may receive the upper portion of the plate 13, as shown in Figure 2.

Projecting outwardly from the angular plate 13 is a ledge 14 which is adapted to receive the bar 7 when the sash 1 is 1n closed position and retain it there while also in a measure locking said bar there with, as shown in Figures 1 and 3.

On the side of the bar 7 towards the sash 1 is the depression or swell 15 which is so positioned that when said sash is closed said swell is adapted to contact freely with the adjacent side of the plate 13 so holding the bar in tight position while occupying the ledge 14:.

It will be seen that when the dog is released from the plate, the bar may be moved laterally on said bar to the right or left and consequently in the arc of a circle, its motion being oblique, and as it rides on the plate 13 as a runway, it pushes out said bar and the upper sash and when it forms a right angle with said sash the latter is opened, as shown in Figure 2.

Then the dog 12 is operated so that its head tightens against the contiguous part of said plate and thus the bar is locked and the sash held in its open position. lVhen the bar is unlocked from the plate the former may be moved obliquely as before to the right or left and so the sash is drawn in when the bar is raised clear of the plate and folded against the latter and seated and held by the ledge 14, the swell 15 bearing against said plate, and thus the sash is held tightly in closed position.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

l. A device for operating a swinging window sash consisting of a bar pivotally connectible with one sash, a plate on the other sash, said bar being freely engaged withsaid plate and slidable in the arc of a circle whereby the swinging sash is operated by the movement of said bar, and means pivov ally mounted 011 the under side of the said bar for locking the same.

2. A device for operating and locking a swinging window sash consisting of a bar pivotally connectible with said sash, a plate like member on the other sash, said bar being freely engaged with said member and slidable thereon in the arc of a circle whereby the swinging sash may be operated by the movement of said bar, and a cam memher on said bar adapted to interlock with said member.

3. A device for operating and looking a swinging window sash consisting of a bar pivotally connectible with the meeting ra l of said sash, and laterally movable in the are of a circle, a plate like member connectible with the meetin rail of the other sash, said bar having herein a recess in which the said member is freely received forming a runway for said bar, and a cam member on said bar adjacent to said recess adapted to engage said plate like membe and thus lock said bar in either of the open positions of said swinging sash.

4. In a device for operating a swinging window sash, a bar pivotally connectible with the latter, a plate-like member on the other sash, a rest on said member to support the bar in the closed position of the sash, and a projection on the side of the bar adapted to be engaged with said member and cooperating with said rest to hold the bar in tight position while occupying sai-l rest.

5. In a device for operating a swinging window sash, a bar pivotally connectible with the latter, a plate-like member on tlr: other sash, a rest on said member to support the bar in the closed position of the sash, a projection on the side of the bar adapted to be engaged with said member and cooperating with said rest to hold the bar in tight position while occupying said rest, and a swell on the side of said bar to contact with said member.
